Systems and methods for liner braiding and resin application

A method of making a tank for storing compressed fluid, the method comprising:

• generating a plurality of resinated braid layers on an elongated liner, the liner comprising a hollow body defining a plurality of successively alternating connector portions and tubing portions along a length of the liner, with the connector portions having a smallest first diameter than a largest second diameter of the tubing portions and with adjacent connector portions and tubing portions coupled by respective taper portions, a plurality of the connector portions comprising a flexible corrugated portion, the liner configured to be folded such that the tubing portions are disposed parallel and adjacent to each other with the connector portions forming a bend, the generating a plurality of resinated braid layers on the liner including:
• calculating a size ratio based on the smallest first diameter and the largest second diameter of the liner;
• selecting a braid material, the braid material having a tensile strength;
• calculating a strength ratio based on the tensile strength of the braid material and a selected target strength threshold for the tank;
• determining an optimal braid angle for the smallest first diameter portions of the liner based on the calculated size ratio;
• calculating a braid jamming value defining a ratio of a minimum aspect ratio on the bend without braid jamming and a maximum aspect ratio on the bend without braid jamming, the ratio based on size ratio based on the smallest first diameter and the largest second diameter of the liner and based on the determined optimal braid angle on the smallest first diameter portions of the liner;
• identifying a target value of a minimum aspect ratio on the bend without braid jamming that will prevent the braid from jamming;
• determining a value for maximum aspect ratio on the bend without braid jamming based on the identified target value of the minimum aspect ratio on the bend without braid jamming;
• determining a number of braid layers necessary to obtain a full braid coverage on the liner;
• determining a number of braid carriers based on the calculated strength ratio, the braid jamming value, the determined number of layers necessary to obtain a full braid coverage on the liner, and the determined minimum aspect ratio on the bend without braid jamming;
• determining a yarn weight based on the strength ratio, the determined number of braid carriers and the determined number of layers necessary to obtain a full braid coverage on the liner;
• generating a plurality of braid layers over the liner comprising the selected braid material, with the number of braid layers corresponding to the determined number of layers necessary to obtain a full braid coverage on the liner and with the braid layers being braided corresponding to the optimal braid angle, the determined number of braid carriers and the determined yarn weight;
• and
• applying resin to one or more of the generated braid layers.
